1 To all whom it may concern:

Be it known that I, Ilnncnna \V. JUNK, a citizen of the United States, residing atv 'lo ledo in the count) of Lucas and State of ()hio have invented'certain new and useful Improvements in Apparatus for Vacuum- Qleaners, of which the following is'a specilication reference being had therein to the accompanying drawing.

This invention relates to a device for causing an air suction through a cleaning apparatus, and the main object of the same is to produce a device which can be attached to a water spigot so as to use the water to cause a suction.

panying drawing wherein:

Figure 1 is a longitudinal sectional view of the attachment and shows same applied to a water spigot. Fig. 2 is a transverse sectional vie i along the line A-A in Fig. 1, looking down.

In the accompanying drawing the. numeral 1 indicates atube which is preferably formed of metal and has leading therefrom a second angular tube to which av flexible pipe 3 is attached. The upper end of the tube is internally threaded and has fitted therein. a core which is provided with a central opening 4 the lower portion thereof being enlarged and provided with spiral grooves as shown by t. A spiral sleeve which. is provided with a tubular extension (3 is threadedwithin the portion 1'" of the central opening of the core and has its upper end extending through the portion at. A threaded collar 7 .is placed upon the end of the portion (3 and is rotatably held thereon by means of a flange 8 formed upon the outer end of the tube 6. This collar is similar-t0 the collars used on a hose to attach the same to a spigot.

The operation of the device is as follows: The collar 7 is screwed upon the end of a spigot and a suction cleaner is attached to the end of the flexible hose 3 and the water turned 011. ll hen the water passes through the tube Git, strikes the spiral sleeve 7 which causes the ater to have a whirling motion as it passes through the pipe 1. This causes an .fll. suction through the pipe tube and hose 3 which operates any desired type .()f vacuum cleaner. It should be noted th t; th pipe 2 is at anupward angle sons to vent any danger of the water getting the same.

if desired the hose may be used for cleaning without attaching the same to a cleaning machine by placing the end of the hose proagainst the article. to be cleaned, thus causother end at said core, and a threaded sleeve for securing said deviceto a water spigot.

2. device of the character described comprising a mainpipe. asupplcmental pipe, a core held within said main pipe, a spiral sleeve held within said core, and means for connecting said sleeve with a supply.

3. A. device of the character described comprising a main pipe, a supplemental pipe,

source of fluid a core removably held within said main pipe,

said core provided with a. central opening terminating at its inner end in an enlarged spiral opening, a spiral sleeve fitting within said spiral opening and provided with a tubular extension passing through said cen- 5 tral opening, and a means secured to the outer end of said tubular extension for se curing said device to a spigot.
